TAVR which is commonly known as Transcatheter aortic valve replacement is a medical subroutine that helps in put back narrowed aortal valve with an artificial valve . The condition of narrowed aortal valve is squall as aortic valve stenosis , in this condition the aortal valve go wrong to open when required . The hokey valve is made from brute tissue and spread by rights when postulate . Some citizenry also call this replacement operation TAVI i.e. transcatheter aortic valve nidation .
TAVR is extremely recommend to patient who are at a higher risk of facing major complications from the open affectionateness surgery . In simple words we can say that , the routine is very helpful for the great unwashed who are not medically fit to undergo the open heart surgery . The determination of performing transcatheter aortal valve replacement is taken only after detailed discussion with multiple doctor and center surgeons . These doctors weigh all the important aspect of patient health and then commonly decide the appropriate treatment option for the affected role . Transcatheter aortic valve replacement procedure is very effective in eliminate all the terrible symptoms of aortal valve stenosis , also it drastically increases the natural selection rate of patient who are suffering from this severe heart upset , but are not recommended to undergo open substance surgery .
generally there are four significant approaches of performing TAVR or transcatheter aortic valve replacement :
Transfemoral Approach
This is one of the simple and highly recommend approach path , which is used in more than 90 % of the surgeries . In this procedure , a hollow tube like structure is firmly inserted in the mole or the femoral artery of the patient role . Further , the unreal valve made from animal tissue paper in compressed form is placed in the catheter , which is slow directed inside the feign aortal valve . Once the valve reaches the appropriate place , it expands automatically and all the catheters that are introduce in the patient ’s dead body are removed one after the other .
This function is chiefly performed by give local anaesthesia or botheration medicines ; it does not require endotracheal intubation or the general anaesthesia . A team of specialists like cardiac anesthesiologists , interventional philia medical specialist , sawbones and mental imagery specialists work in sump to rank valve successfully . This procedure is highly recommend to patient role have small watercraft in the pelvis , which is not enough to tuck valve catheter .
Trans-Subclavian Approach
Unlike the transfemoral coming , this procedure is performed by giving worldwide anaesthesia and endotracheal electron tube . The procedure is performed only when the right or left subclavian arteria are enceinte enough to surpass the valve catheter . A minor cutting is made above the subclavian arteria through , which a hollow tube is passed to aorta . Animal tissue in compact form is inserted in aorta through vacuous tube and once the valve reaches the right position the valve expands . It is only when the valve starts to work properly empty tube is slowly absent from the chest part .
Transapical Approach
This procedure is also channel by giving general anaesthesia and with the help of endotracheal subway . In this process , slit is made in the ribs neighborhood and then a light free weight vacuous pipe is insert in the opening of the heart . Like other procedures , once the valve reaches the ask positioning it exposit automatically and then the vacuous tube is slowly remove from the organic structure .
Transaortic Approach
Like the above two procedure , Transaortic Approach is also perform with general anaesthesia endotracheal thermionic valve . In this procedure , incision is made in watt second - shape and on the breastbone . Further through this incision hollow tube is insert into the patient ’s body for placing contrived valve . After the compressed valve is placed properly the tube is take successfully .
